It took all day to reprofile my HairyCarry but it did a fabulous job. Nice and straight and very very sharp. A 5X loupe or magnifying glass is also invaluable to see how you start with one bevel then it turns to 2 beveled angles and then the new bevel gets bigger until it takes over the first. I also picked up a coarse diamond stone but have worn it down to a fine diamond. It is worth buying the diamond on it's own but the whole diamond kit is 100$
I would love an edge pro. My buddy has one for sale but it is expensive even used.
A belt sanded can get them just as sharp much faster but it is not quite as even looking. Also you cn screw up pretty fast with a powered belt
